(a) Air in a piston-cylinder device undergoes a process that follows the relation shown in Figure 1 to a final pressure and temperature of 350 kPa and 270 °C, respectively. Determine the work required for the process, in kJ, if the air is initially at 0.25 MPa and 350 K. Assume the process is in an ideal gas state with an initial mass of 5 kg. Gas PV" C const. Figure 1
